I'm on the fence with this. I've seen enough requests for it that I'm
fairly sure that a suitably buried (--expert & --pgp2 & warning) v3
key generation would be useful. That's the whole idea of --expert
anyway: to enable doing silly/broken/incompatible things that only
people who know what they are doing should do. The fact that it would
be "useful" is also what worries me...
The code change itself is pretty trivial - there would be more code
added to print suitably lurid warning messages than there would be
added to support generating v3 keys :)
With regards to using v3 keys on Usenet control messages, while I
think that v3 keys were deprecated for many good reasons, I have some
experience with this usage and it's one of the few things I'd be
content using v3 keys for. There is such a large installed base of
(sometimes half-forgotten) news servers still running PGP 2 that it's
safe to say that upgrading any time soon is just not in the cards.
Russ, what I'd ask you to do is to send each gnu.* control message
twice - each signed with a different (one v3, one v4) key. At least
then Usenet can start on the path of using v4 keys.
